Armstrong Whitworth

Sir W. G. Armstrong, Whitworth & Co. (commonly 'Armstrong Whitworth' or 'Armstrong Whitworth Engineering') was a major Tyneside engineering firm formed in 1897 by the merger of the Armstrong and Whitworth firms. Its principal works at Elswick and Scotswood, Newcastle upon Tyne, built warships, armaments, motor vehicles and (after 1918) locomotives.

The firm built locomotives for British and overseas customers, particularly during and after the First World War when it expanded into general engineering to compensate for declining warship orders. Notable Armstrong Whitworth products included the diesel-electric prototype Hardwicke for the LMS in 1933 and several batches of the ROD 2-8-0 under wartime contract.

The firm's locomotive interests were absorbed into Vickers-Armstrongs in 1927 and most of the locomotive work transferred to Tyneside subsidiaries. The Newcastle site continued in heavy engineering and shipbuilding through the twentieth century.
